However, in the conventional bay window, since the skeleton composed of the upper frame, the lower frame, etc. is usually formed of a metal shape member having good thermal conductivity,
A large amount of heat goes in and out through the shape members, and even if the airtightness is achieved as described above, there is a limit in improving the heat insulating property. Further, since the vertical frame is formed with a cutout portion into which the table plate is fitted and the lower side of the table plate is the outdoor side, the gap between the vertical frame and the building frame and the table plate of the vertical frame. There is a problem that the outdoor side and the indoor side communicate with each other through the fitting notch and air or heat easily enters and leaves, and the heat insulating property deteriorates.

Therefore, an object of the present invention is to prevent heat from entering and exiting through the shape members, and to provide the space between the vertical frame and the frame of the building and the outdoor side and the indoor side through the table plate fitting notches of the vertical frame. Another object of the present invention is to provide an adiabatic exit window capable of sufficiently improving the adiabaticity by preventing the entry and exit of air or heat.

Further, the vertical frame 4 and the upright 5 are formed hollow, and lids 34 and 35 having airtight materials 32 and 33 for hermetically closing the vertical frames 4 and 5 are attached to the upper and lower ends thereof. Therefore, inflow and outflow of air or heat through the hollow portions h of the vertical frame 4 and the upright 5 can be prevented, and the sealed hollow portions h can be used as a heat insulating space, thereby sufficiently improving heat insulating properties. be able to. Since the upper ends of the vertical frame 4 and the vertical 5 are located on the indoor side under the top plate 12 and the lower ends are located on the outdoor side under the table plate 20, they are formed so as to communicate with the hollow portion h and the hollow portion h. Air and heat are likely to flow in and out through a processed hole such as a screw hole, and if the lids 34 and 35 are provided only on the lower ends of the vertical frame 4 and the upright 5, the vertical frame 4 and the lower frame may be provided. From the upper end of 5 to the outdoor section 4
The air on the indoor side enters the hollow portions h of x and 5x, and heat flows in and out through the outdoor shape members 4x and 5x.
There is a problem that a sufficient heat insulation effect cannot be obtained.
And airtight materials 32, 3 on both the upper and lower ends of the cubic 5
The above problem can be solved by providing the lids 34 and 35 through 3 and sealing the hollow portion h. This is particularly effective for the cubic 5 having a large volume in the hollow portion h.

In particular, since the vertical frame 4 is provided with an airtight piece 41 which is in contact with the lower surface of the table plate 20 and seals the gap s between the vertical frame 4 and the building frame 1 of the building, It is possible to reliably prevent air or heat from entering or exiting between the outdoor side and the indoor side through the gap s between the frame 4 and the frame 1 of the building and the table plate fitting notch 42 of the vertical frame 4, and thus to improve the heat insulation performance. A dramatic improvement can be achieved.
